Process for the Preparation of Sn-BEA Via Post-Treatment Process

[0075]Post-synthesized Sn-BEA zeolite / zeotype materials were prepared according to the procedure described in ChemSusChem 2015, 8, 613-617. A commercial BEA zeolite having the *BEA framework (CP7119, Zeolyst, Si / Al=12.5, NEW-form) was initially calcined at 550° C. for 6 h to obtain the zeolite on its H+-form, followed by acidic dealumination as follows: 10 g of concentrated nitric acid (HNO3, Sigma-Aldrich, ≥65%) was added per 1 g of zeolite *BEA material and the suspension was heated to 80° C. for 12-24 h. The dealuminated solid was recovered by filtration, extensively washed with deionized water and calcined at 550° C. for 6 h using a heating ramp of 2° C. / min. Tin was then introduced in the created vacancies in the zeolite framework by incipient wetness impregnation using tin(II) chloride in solution as the tin source. The solution was prepared by dissolving 0.128 g of tin(II) chloride (Sigma-Aldrich, 98%) in 5.75 mL...

Preparation of Zr-BEA Via Post-Treatment Process

[0076]The same procedure as for 1A was followed, except the 0.128 g of tin(II) chloride was replaced with 0.121 g ZrOCl2·8H2O or ZrCl4 was used as the source of zirconium.

Abstract

New process of producing alpha-hydroxy compounds from sustainable resources useful as platform chemicals, such as hydroxy analogues of amino acids or polymer precursors.

Description

TECHNICAL FIELD[0001]The present invention regards a new process for producing alpha-hydroxy compounds useful as platform chemicals, such as hydroxy analogues of amino acids or polymer precursors.BACKGROUND[0002]In animal nutrition there is a great demand for feed additives. A group of feed additives are amino acids and hydroxy analogues of amino acids. In particular, there is a demand for biobased feed additives made from, renewable, sustainable raw materials. The amino acids Leucine (Leu), Isoleucine (Ile), Valine (Val), Phenylalanine (Phe) Histidine (His), Methionine (Met), Cysteine (Cys), Glutamic acid (Glu), Tryptophan (Trp) and Tyrosine (Tyr) are all interesting as additives in animal feed. But also the corresponding amino acid analogues may be used. In order to be useful as feed additives, low cost processes for producing the amino acids or the alpha-hydroxy analogues are needed. Known processes include fermentation and various processes of chemical synthesis.[0003]Both Lysin...
